Genetics Drives Bird MigrationReveals what Doctor Ursula Munro found in her examination of the ability of some animals to migrate over thousands of kilometers. Unusual thing about the silvereye bird; Importance of knowing where the animal ...

This study entails an evolutionary analysis of 42 genes associated with pulmonary fibrosis across 45 mammalian species. Twenty-one genes in cetaceans exhibited accelerated evolution, featuring specific amino acid substitutions in 14 of them. Primarily linked to the development of the respiratory system a...
Complexity of avian evolution revealed by family-level genomes Using intergenic regions and coalescent methods to analyse the genomes of 363 bird species, the authors present a well-supported tree confirming that Neoaves experienced rapid radiation at or near the Cretaceous–Palaeogene boundary. ...
This was demonstrated in a study of a population of hamadryas baboons, and results suggested recent evolution of female-biased dispersal in this species (Hammond et al. 2006). In several primate species both sexes disperse, and thus the dispersal distance and frequency of each sex is of ...
Population genetic structure - the distribution of genetic variation in time and space - affects how a species responds to selection pressures, and so shapes its evolution [9]. Studying the population genetics of parasites in wild animals has several benefits. First, it provides an insight into ...
Before Darwinian evolution became the prevailing theory of the field, French naturalist Jean-Baptiste Lamarck theorized that acquired traits could, in fact, be inherited; while this hypothesis has largely been unsupported, scientists have recently begun to realize that Lamarck was not completely wrong....
Evolution and its elements of natural selection, population migration, genetic drift, and founder effects have shaped the world in which we practice public... Gilbert S. Omenn and Peter T. Ellison - 《Proceedings of the National Academy of Sciences of the United States of America》 被引量: ...
Natural selection and evolution Main article: Evolution Further information: Natural selection Mutations alter an organisms genotype and occasionally this causes different phenotypes to appear. Most mutations have little effect on an organism's phenotype, health, or reproductive fitness. Mutations that do ...
Red Queen host–parasite co-evolution can drive adaptations of immune genes by positive selection that erodes genetic variation (Red Queen arms race) or results in a balanced polymorphism (Red Queen dynamics) and long-term preservation of genetic variation (trans-species polymorphism). These two Red...
